Line 73: − − − Simon did tests and report:+ − − what I did today to get a bit of a feeling of what is needed to port Read was looking at the evince bidings through introspection. So first, hmmm what is the gi repository called? − − In Fedora you can have a look at '/usr/lib/girepository-1.0/' and find out that there is a EvinceDocument-3.0.typelib and a EvinceDocument-3.0.typelib. If we have a quick look at [1] we find out that the .typelib is a Binary version of the invocation info. Ok let's try this: − − from gi.repository import EvinceDocument − dir(EvinceDocument) − − from gi.repository import EvinceView − dir(EvinceView) − − Works! − − Looking at the invokations in read/evinceadapter.py I did extract the calls we did previously on the evince module (e.g. evince.View()) and checked if they were present, too. − − The evince.View() is now EvinceView.View(). − − Furthermore are present: − − help(view) − view.set_model − view.can_zoom_in, view.can_zoom_out − view.zoom_in − view_zoom_out − view.find_next − view.find_previous − view.scroll − view.copy − view.find_set_highlight_search − − I could not find: update_view_size, find_changed − − Some further transitions: − − evince.JobFind -> EvinceView.JobFind − evince.Job.scheduler_push_job -> EvinceView.Job − − I could not find: evince.SIZING_* (e.g. evince.SIZING_BEST_FIT) − − More info on the EvinceView API are at [2]. − − − And then I came across an hard one (which I have not solved yet): − − I could not find out how 'evince.document_factory_get_document(file_path)' should be called now. Looking at the API it should be maybe something like EvinceDocument.factory_get_document, trying that: − − >>> EvinceDocument.factory_get_document − Traceback (most recent call last): − File "<stdin>", line 1, in <module> − File "/usr/lib/python2.7/site-packages/gi/module.py", line 243, in __getattr__ − return getattr(self._introspection_module, name) − File "/usr/lib/python2.7/site-packages/gi/module.py", line 105, in __getattr__ − self.__name__, name)) − AttributeError: 'gi.repository.EvinceDocument' object has no attribute 'factory_get_document' − >>> − − Hmm, I did get the sources, then to have a look because the .typelib is a Binary version of the invocation info and therefore I need to have a look at the .gir file to dig a bit deeper. After installing all the dependencies I did a './autogen.sh --enable-introspection' and run 'make' and had a .gir file placed in libdocument/EvinceDocument-3.0.gir. Looking at the definition it says: − − <function name="factory_get_document" − c:identifier="ev_document_factory_get_document" − introspectable="0" − throws="1"> − − Hmm, so it should not be available 'introspectable="0"'. Why, how, this exercise is left to the reader, I am a bit stuck on this :) − − A good resource for asking related is questions is #introspection on GimpNet. I have attached the chat I had with Tomeu about that issue. − − Regards, − Simon − − − − [2] http://developer.gnome.org/libevview/stable/ − − [3] http://developer.gnome.org/libevdocument/stable/libevdocument-ev-document-factory.html − The gir file is installed with the package evince-devel in /usr/share/gir-1.0/EvinceDocument-3.0.gir+

Not directly related. Evince developers have a request to support epub format [https://bugzilla.gnome.org/show_bug.cgi?id=539347].
[1] http://live.gnome.org/GObjectIntrospection/Architecture
We are implementing our own epub reader displaying it with webkit. If implemented in evince, we can simplify our code a lot.
